4 Claims.

This invention relates to a sacroiliac belt having crotch straps.

The principal object of the invention is to provide a. sacroiliac belt with crotch strap means which prevents the belt from riding up, but accomplishes this result without discomfort to the patent. A particular object of the invention is to locate these crotch straps so that they encircle the patients legs below the patients buttocks (the gluteus maximus muscle) in order that the belt may be comfortably worn, and particularly that the patient may move about and sit comfortably.

This invention consists in a belt having a rear band portion worn above the buttocks, and crotch straps having connections to the belt between which they at least partly encircle the patients upper thighs, but lie below the buttocks.

In the drawings:

Fig. 1 is a front view of my inproved belt as it appears in use, the outline of the patients body being shown diagrammatically.

Fig. 2 is a side view of my improved belt as it appears in use, the outline of the patients body being shown diagrammatically.

Fig. 3 is a plan view, on a reduced scale, of the open belt.

The sacroiliac belt indicated generally by the reference character I is of the type described in my prior Patent No. 2,543,095, issued February 27, 1951, and entitled sacroiliac Belt. The belt comprises a band I 0 which encircles the body and has a central apex I I disposed to rest over the patients sacrum and above the buttocks or gluteus maximus muscle indicated by reference character 2|. The belt has widening end portions I2 provided with stiffening means or lines of stitching I3 to which tension straps l4 and buckle straps I5 are anchored. In open plan the belt describes the form of a shallow V as shown in Fig. 2. When worn, the end portions I2 of the belt are downwardly inclined from the apex I I to dispose the tension straps over the lower abdomen of the patient as shown in Figs. 1 and 2.

In order to securely anchor the belt against riding up I provide crotch straps I8. These are detachably connected with the belt, as by means of the snap fasteners I9 which are anchored to the lower margins of the end portions I2 of the belt. Second anchorages for the straps comprise buckles 20 anchored to the belt along the lower margin thereof but spaced somewhat toward the apex II. Both anchorages thus lie forwardly of a transverse center line through the patients body. The spacing of the buckles 20 from the snap fasteners I9 is such that when the straps I8 are passed about the upper thighs of the patient, and connected to the buckles 20 the straps I8 will lie below the patients buttocks or gluteus maximus muscles. As the belt I0 encircles the body substantially above the buttocks, no strap or belt passes over the buttocks. Accordingly, the belt may be worn for long periods of time, and the patient may seat himself and otherwise move about in complete comfort. The belt and straps are disposed over body portions which have little movement in the normal activity of the body, hence chafiing is reduced to a minimum.

As best shown in Fig. 1 the straps I8 constitute an extension of the lower margin of the belt. Accordingly, strap tension ha no dislocating efiect on the belt position. A properly positioned strap will follow the muscle fold between the buttocks and the leg.

I claim:

1. A device of the character described comprising a sacroiliac belt having at its ends tension straps for connecting the ends of the belt across the lower abdomen of the patients body, in combination with first and second crotch strap connections, both of which are proximate the same end of the belt, the connection farthest from the end being inclined away from such end at an angle to the longitudinal center line of the belt, and a crotch strap attached to said connections in a position to at least partly encircle the upper thigh of the patients leg between said connections, said strap extending from the connection farthest from the end of the belt downwardly to lie below the patients buttocks and thence from between the patients legs upwardly to the connection nearest the end of the belt.

2. A device of the character described comprising a belt having left and right forward end portions with detachable connecting means and having an intermediate portion adapted to be disposed at the rear of the patients body and passing above the patients buttocks, and a crotch strap having terminal connections to the belt both of which are attached to the same forward end of the belt, whereby to be forward of a transverse center line through the patients body, said strap having a downward and rearward projection from one of said terminal connections, whereby to lie below one of the patients buttocks and having an upward and rearward projection from between the patients legs toward the other of said terminal connections whereby to encircle at least partially the upper thigh of the patients leg between said connections.

3. The device 01 claim 2 wherein said connections are at the lower margin of the belt, the forward terminal connection comprising a pivot on which the strap is free to assume a position constituting an inward and rearward extension of said lower margin.

4. The device of claim 2 in further combination with a second crotch strap having terminal connections both attached to the other forward end portion of the belt and having a. downward and rearward extent from. one of its terminal connections whereby to lie below the patients other buttock, and having an upward and rearward projection from between the patients legs toward the other of its terminal connections, whereby tov encircle at least partially the upper thigh of the patients other leg between said terminalconnec- 4 tions, the connection to which each strap extends upwardly and rearwardly as aforesaid comprising means for pivoting the respective strap terminals with reference to the belt end portions to which RALPH E.
